50 amp automatic transfer switch for 120/240V RV shore power and generator power systems. Provides automatic generator-dominant source switching with reverse polarity and open ground protection. This model does not provide surge protection.
The Southwire 40101-001 is a 50 amp automatic transfer switch designed for RVs with both shore power and onboard generator power. It automatically switches the RV’s AC power source between shore and generator power, helping eliminate the need to manually move cords between sources.
This model is generator dominant. When generator power is energized, the transfer switch changes to generator power after a 30-second delay. When the generator shuts down, shore power is restored after a short 3-4 second delay.
Automatically switches between shore power and generator power
Designed for 50 amp RV electrical systems using 120/240V service
Provides reverse polarity and open ground protection on shore power
Transfers to generator after 30 seconds and returns to shore after 3-4 seconds
The Southwire 40101-001 is commonly used in motorhomes, fifth wheels, and other RVs with a 50 amp shore power connection and onboard generator. It is intended for hardwired installation between the shore power input, generator output, and RV main distribution panel. This model is a transfer switch, not a transformer adapter. It does not change voltage, convert 30 amp service to 50 amp service, or provide surge suppression.
• One Southwire 40101-001 50 amp automatic transfer switch • Installation documentation as supplied by manufacturer
This transfer switch is hardwired between the RV’s shore power input, generator output, and main AC distribution panel. Verify 50 amp service rating, 120/240V wiring, conductor size, neutral/ground routing, generator compatibility, enclosure space, and strain relief requirements before installation. This model does not include surge protection. If surge, low/high voltage, open neutral, or full EMS-style protection is needed, use the appropriate Southwire Surge Guard protection device or transfer switch model.
Transfer switch installation involves 120/240V AC power, shore power, generator power, high-current wiring, neutral/ground routing, and RV electrical code requirements. Installation should be performed by a qualified RV technician or electrician familiar with 50 amp RV electrical systems. Disconnect shore power, generator power, inverter power, and battery power before servicing.
The Southwire 40101-001 is a 50 amp, 120/240V automatic RV transfer switch with reverse polarity and open ground protection. It is not a transformer adapter and does not provide surge protection. Verify service rating, generator compatibility, protection needs, mounting space, and wiring before ordering.
